The external iliac artery is a large blood vessel which originates from the bifurcation of the common iliac artery. Then the external iliac runs down obliquely outwards, giving off two branches along its way: the inferior epigastric artery and the deep circumflex artery, which supply blood to the muscles and skin in the lower abdominal wall. Passing beneath the inguinal ligament in the lower part of the abdomen, the external iliac artery becomes the femoral artery, which supplies oxygenated blood to the leg. The external iliac artery is a paired artery, meaning there is one on each side of the body.
